ORE PULVERIZER.

Application filed November 20,1923, SerialNo, 675,884. Renewed January12, 1925.

To all whom it may concern:

lie it known that l. Grouch E. C. Rousseau, a citizen of the UnitedStates, residing at tltl'tlllltnl't). in the county of Sacramento, Stateof California, have invented certain new and useful lm n'oi'eincnts inOre Pulverizers: and 1 do hereby declare the following to he a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

- s This invention relates to new and useful improvenn nts in oretreating machines and particularly to devices or machines for crushingore which contains precious metals. One object is to provide a device ofthis Character wherein. the means for feeding the ore to the crusherarranged to discharge the ore directly in front of the crushing roll,and wherein a movable auxiliary crushing means is disposed between theroll and I the drum, at a point diametrically opposite the feed, toproduce a more ellicient crushing action. Another object is to provide adevice of this el'iaracter wherein the crushing roll normally gravitatesinto contact with the interior of the drum and is capable of readyself-adjustment so that should too much ore h delivered into the devicethe roll will rise without allccting the driving thereof.

A further object. is'to provide a crushing roll wherein the periphery isformed of readily removable sections having large opcrating faces, whichpermit easy and quick. replacement. of any portion when worn.

Other objects and advantages will be apparent from'the followingdescription when taken in connection with the accompanying drawings.

In the. drawings:

Figure. 1 is a side elevation of an ore crushing nnu-hineimade inaccordance with the present invention.

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1.

Figure 3 is a vertical sectional view on the line 3--3 of Figure 2.

Figure 4; is a horizontalsectional View on the line -1---,! of Figure 2.

Referring particularly to the accompanying drawings, the supporting basefor the ore crusher consists of the cementblOCliS 1O. 11, 12, andlii.The hlooks and 1 are of the same height. and mounted on the upper an ofeat-h of thcsc hloclts is a bearing block 14, which supports the,trunnions of the drum supporting and guiding rollers 16. On the block 12are the bearing blocks .cul'cd a second ring 21, having a ciroumferential series of gear teeth 22 which mesh with the teeth of the gear 19,and by means of -which gear 19 the drum is rotated in the direction ofthe arrow in Figure 3. The-inner face of the ring 20 is formed with acircumferential ly extending groove or channel 23, to which referencewill be made later. On the upper face of the block 11 there is alsomounted a bearing block 2% which supports the guiding rollers 25, saidrollers also being arranged to support the drum. In the upper face ofeach of the blocks 10, 11, 12, and 13, there are formed the grooves 26to receive the lower portions of the rollers. It will be noted that thecenter of the peripheral face of the outer ring 21, on which are formedthe teeth 22, is in the form of a. circumferentially extending rib 27,which produces the circumferential ledges or open-sided grooves 28, atthe opposite sides thereof. It is within these grooves that the guidingand supporting rollers 16 and engage. Secured to the opposite sides ofthe rings 20 and 21, are the'disks 29, each having a central opening 30through which theore to be crushed is fed. The peripheral edge. portionsof these disks 29 extend beyond the periphery of the ring 2-1 and lieagainst the outer side faces of the rollers 16 and 25, whereby to formthe outer walls of the grooves or channels 28, to retain the rollers anddrum in proper relation to each other. Formed in a circular series ineach of the disks 29, adjacent the periphery thereof and inwardly of theinner face of the inner ring 20. are the elongated openings 31, withineach of which is secured 'a screen 32. Movably mounted on the disk, ateach of the said openings 31, is a cover plate 33, arranged to he swunginto and out of covering relation to the opening.

Disposed within the drum is a crushing wheel, designated as a whole bythe numeral 84, and this wheel includes a huh 35, in the form of a disk;a rim 36; and the-spokes 37, the latter being secured to and extendingbetween the hub and rim, as clearly seen in Figures 2 and 3. Engaged onthe periphery of the rim 36 are the segments 38, each having abifurcated lug on its inner concave face, at 89, for straddlingengagement on the rim, a bolt 40 being engaged through the lug and rim.By this construction a worn segment may be easily removed and replacedwhen it is necessary. The hub 35 is fixed on the shaft 41 which extendstransversely of the drum and projects through the openings 30 of thedisks 29, said shaft being preferably located normally at the lowersides of said openings. Secured to the block 11, and extendingvertically at the opposite sides of the drum, are the longitudinallyslotted uprights 42, the slots 43 of which have the slidable bearingblocks 43 therein, and-which.blocks rotatably support the end portionsof the shaft 41. One end of the shaft 41 is provided with a universaljoint memebr 44, as seen in Figure 2, and supported in the upper end ofan upright 45, which is mounted on the end of the block 11, is a driveshaft 46. On the inner end of this shaft 46 the sleeve portion 44,, ,ofthe universal joint 44 is slidably keyed or splined, while on the outerend of the shaft,is fixed a gear 47, meshing with a gear 48 on theadjacent end of the shaft of the gear 19, whereby power applied to theshaft of the gear 19 will be transmitted to the shaft 41, to rotate thecrushi wheel 34, in the direction of the arrow of Figure .3", while atthe same time the drum will be rotated. The gearing 47 and 48 is suchthat the-' 'crushing wheel will rotate at the rate or ratio of 12 to 1,with respect or relation to the drum. The universal joint 44 permits thewheel 34 and its shaft 41. to rise and fall without interference withthe gears 47 and 48. Secured to the outer face of each disk 29,outwardly of the series of openings 81, is an outwardly flared ring orflange 49,

which serves toguide the pulverized material away from the side of thedrum, as said material flows out through the screens.

Disposed above the drum is a hopper 50 for containing the ore to becrushed, said hopper being supported on the uprights 51. The bottom ofthe hopper is provided with a pair of downwardlyextending dischargespouts 52, which lead into the openings 30, and connect with the troughsor chutes 53,

said chutes extending downwardly and forwardly to points over the spacebetweeen the wheel 34 and the inner face of the ring 20,

so that the ore will be deposited at the proper position to pass beneaththe crushing roll, as will be readily understood.

Loosely disposed between the crushing wheel 34 and the innerface of thering 20, at a point approximately diametrically opposite to the point ofreception of the ore to be crushed, is a triangular, block 54,

which normally gravitates aga'nst the wheel and ring so that the materiawhich has been crushed between the wheel and ring the rim of the drum,and a floating crush ing element between the wheel and rim at a pointopposite the point wherein the ore is fed.

2. An ore crusher including an outer rotatable drum and an innercrushing roll, said roll including a rim, and a plurality of segmentalblocks each, having a pair of spaced lugs straddling the rim and securedremovably thereto, the working faces of the blocks forming a continuouscrushing peripheral face. j"

-3. An ore crusher including an outer rotatable drum, an inner crushingroll dis- "posed within the drum and gravitatin into contact with theinterior of the drum, and a wedge between the crushing roll and theinterior of the drum and cooperating therewith for crushing ore.-

4. An ore crusher includin an outer rotatable drum, an inner rotatablecrushing roll gravitating into contact with the inner circumferentialface of the drum, means for of the drum, and an auxiliary crushing meansbetween'theperiphery of the roll and p the said circumferential face ata point diametrically opposite to the said feeding means.

In testimony whereof, I aflix my signa' ture, in the resence of twowitnesses.
